TYPE-CASE.

SPECIFICATION forming part of Letters Patent No. 278,782, dated June 5,1883.

Application filed September 7,1882. (No model.) I

To all whom it may concern;-

Be it known that I, CHARLES C. DOTEN, of Plymouth, in the county ofPlymouth, and in the State of Massachusetts, printer and pub lisher,have invented certain new and useful Improvements relating to TypeCases, of which the following is a specification.

I make the bottom of the typecase of two thicknesses ofwire-cloth ofdifferent-sized mesh and strength.

The following is a description ofwhat I consider the best means ofcarrying out the invention.

The accompanying drawing forms a part of this specification, and is avertical section through a portion of my improved case,

My improved case may be made with the sides and partitions of wood,having the compartments arranged in any ordinary or suitable manner. Forthe bottom I employ two thicknesses of wire-cloth of the same size andshape as the case, laying one upon the other, the lower one beingcoarser and stronger than the upper layer. I securely fasten the edgesof both all around to the frame of the case by nails or staples, and Isecure by the same or diiferent fastening-s a cleat or strip of woodapplied below, so as to support and protect each edge. At each of thecrossing-points of the partitions I introduce a fine wire fastening inthe form of a loop, which takes hold of the joint of the partitions, andalso takes hold of both thicknesses of the wire-cloth. I thus Securethis wire-cloth bottom strongly along the edges, and also at points onlya little distance apart along the bottom of the several partitions.

Referring to the drawing, A is the edge, and

B B some of the partitions, of the case, made of wood and nicely jointedtogether, as usual. C C are the two thicknesses of the wire-clothbottom. D is one of the securing-cleats, and E the fastenings.

G G are the loops of wire embracing the joint or crossing-place ofthepartition B. They extend down through both thicknesses of the wire-clothC, and are tightly strained by the ends being twisted together below.The twisted ends are'then bent up close to the wire cloth.

My improved case is always clean. No apprecia-ble quantity of dust cangather on the narrow rounded surfaces of smooth wires.

I prefer that the wire-cloth be of fine wires and open-wove, so as topresent considerable spaces for the passage of dust; but care must betaken to avoid the use of wire-cloth having so large meshes as to allowthe passage of small type. Brass, as the material for the wires,withstands dampness and acids better than iron or steel; but this pointis not absolutely essential.

WVhen type from standing unused becomes particularly dusty. I can cleanthem by simply shaking the case. While the case is in use the usualmanipulation keeps the type constantly clean.

I esteem this simple and expeditious method of cleaning the type whendusty one of great importance to compositors If bellows are used, I canblow upward from below through the wire-cloth.

As ordinarily used, the openness of the bot tom facilitates the passageof the dust downit ward through it, and the peculiar surface presentedof wire-cloth engages with the parts of the type in contact therewith inthe act of shaking, so as to thoroughly agitate the mass.

Modifications may be made in many of the details. Parts of the inventionmay be used without the whole. I can hem or fold over the edge of one orboth the layers of wire-cloth to insure against fraying. The edge of thebottom may be left a little within the line of the exterior of the case.The edge of the wirecloth may be dipped in melted solder or otherwisesecured by soldering, thesolder being subsequently flattened by rollingor otherwise to reduce the thickness.

I am aware that perforated bottoms for typecases is not broadly new withme, and such feature, broadly, is not sought to be covered in thisapplication.

What I claim as new is 1. A type case having a bottom composed of twothicknesses of woven wire ofdifferent mesh and strength,- and adapted toserve as and for the purposes set forth.

2. A type case having a bottom composed of two thicknesses of wovenwire, the upper finer than the lower, and both secured to the frame incontact, whereby the lower supports the upper, substantially as setforth.

3. In a type-case, and in combination with hand, at Plymouth,Massachusetts, this 29th the ordinary partitioned frame, the duplex dayof June, 1882, in the presence of two subwire-cloth bottoms O C, ofdifferent mesh and scribing witnesses.

arranged as described, and the securing means CHARLES C. DOTEN. 5' D, E,and G, all operating as and for the pur- W'it-nesses:
